Feel like I've made a mistake and getting stressed cause of it

Always wanted a place of my own for me and my daughter so saved up last year and found one looked ok went I went to view it slthough there was no letting agent there just the previous tenant showing me about Was home sick at first but then I felt better now I'm feeling stressed due to the fact I'm still waiting on repairs and have contacted the letting agents and have had no word back starting to think I've made a mistake in getting this house like I should have held out for something else also worried if I'm going to be able to pay everything been ok for the first 2/3 months but now got more bills
